ATTACHMENT FOR PORCH SWINGS Filed July 2, 1928 I l Ill/I 25 ATTORNEY Patented Dec. 2, 1930 UNITED STATES WILLIAM H. FRY, OF KANSAS CITY, MISSOURI ATTACHMENT FOR 'roacn SWI/NGS Application filed July 2, 1928. Serial No. 289,876.

This invention relates to porch swings and especially to that type which is suspended and providedwith a swing propulsion foot rest. 7

The principal object of the present invention is the provision of a porch swing having a seat member carried by a front and rear pair of flexible suspending members and having a swing propulsion foot rest pivotally carried by said seat member and adapted to flex a pair of said suspending members as the same is oscillated.

A further object of this invention is the contemplation of, a porch swing having a swing propulsion foot rest provided with means for vertical and longitudinal adjustment.

A still further object of the present invention is an attachment for a porch swing having a pivotally supported swing propulsion foot rest which when oscillated changes the center of gravity of said swing, thereby causing the swing to oscillate.

Other objects are ease of operation, ease of adjustment, and durability of construction.

With these general objects in view as well as minor objects which will a pear during the course of the detailed specification reference will now be made to the accompanying drawing in which Figure 1, is a perspective view of a porch swing, with some parts partially broken away, embodying this invention.

Fig. 2, is an enlarged fragmentary section taken on line 11-11 of Fig. 1.

Fig. 3, is an enlarged end elevation of a portion of the foot rest.

Fig. 4, is an enlarged fragmentary view showing the slip joint connectlon between the foot rest andthe flexible suspension member.

Similar reference characters designate like parts throughout the several views and numeral 5 designates a seat member having end members 6, and a pair of front and rear flexible suspending members 7 and 8 respectively. These suspending members are preferably made of chains secured at one end to seat member by means of screw eyes 9 and having at their. opposite ends, screw eyes 32 or hooks for attachment to the ceiling. These suppropulsion'foot rest is operated; I

porting members are preferably substantiallyparallel for purposes hereinafter set forth. The front pair ofsuspending members 7, are providedwith elongated links 10 which are preferablypositioned in said chains adjacent their lower ends.

Rigidlyrattached to each ofend members 6', by means of screws 11, is a forwardly-extending bracket 12 having its outer extremity vertically bifurcated. Y Y.

The swing propulsion foot-rest 13 is provided with vertical arms l l pivotally mounted in brackets 12by means of. pivots 15; Intermediate the ends of arms 14 andbelow pivot 15 is a sleevesection 16 by means of which said arm maybe lengthened orshortened at will andsecured in a predetermined position by set screw '17 which is screw threaded in said sleeve section The upper end of arm :14 adjacent the bracket 12 is provided with a series of transverse holes 18 for receivingthe.pivots-15 to support said arm in difl'erent vertical-positions. As: clearly shown in Fig. 1, the upper portionof arm 14: extends above the pivotal point 15 andis pro- 7 vided with a rearwardly extendingfarin 22 having'a vertical opening 19for. thereception of theelongated link-'10eand through which the link is free to'moveas the swing 3 :To prevent unduewear ofarm' 22 and link 10.1 have provided-a suitable bushing, 20 which fits in theopening 19 and around the link 10. Also to prevent accidental pinching of the hands of occupants of the swing a flexible shield 21 which is adapted to cover theouterend of arm" 22 and a portion of the elongated link: 10 is provided. The lower portions 23 of arms 14 arevoppo'sitely disposed and adapted to .slidinglyengage the 'connectingsleeve 24 for longitudinal adjustment. When the members 23 and 24 are properly adjusted as to length the set screws 25 carried by sleeve 24 are securely set against members 23 to hold the parts in a fixed rela- 5 tive position.

Extending forwardly and substantially at right angles to arms 14 are supporting arms 26 and 27 respectively. Horizontally extend-- ing bars 28 are securely attached to supporting arm 26 at one end by means of rivets 29, while the opposite ends of said bars are slidably mounted in loops 30 formed on the upper side of supporting arm 27. With the construction as described and shown it is apparent that the foot rest may be adjusted to swings of different lengths, and when so adjusted, if the bars 28 extend too far through loop 30 a portion of the same may be cut away.

In the operation of this swing the seat member with the foot rest properly adjusted is suspended as described above so that it is free to swing. The operator when positioned in the swing with his feet resting on the bars 28 may oscillate'the swing by pressing forwardly or rearwardly on the bars, thereby causing the foot rest to oscillate about pivots 15. This oscillation in turn causes the flexing of the front pair of suspending members. This flexing of the suspending members and the resultant changing of the relative positions of the seat member and foot rest will disturb the equilibrium of the swing and cause it to oscillate to a degree commensurate to the force applied to the foot rest. Likewise, when the swing isin motion it may be brought to rest by simply applying foot force to the foot rest in counter direction to the movement of the swing.

While the foot rest has been shown and described as flexing the front pair of suspending members, yet it is apparent that the operation would be substantially the same if the rear pair of suspension members was flexed.

I do not limit this invention to the construc tion shown and described, as many modifications may be made within the scope of the appended claim without departing from the 1 spirit thereof.

What I claim is z A porch swing comprising a seat member, a front and rear pair of suspension members for said seat member, a swing propulsion foot rest pivotally carried by said seat member and having a pair of arms extending above the pivot points and engaging the front pair of suspension members and adapted to flex one pair of suspension members forwardly and rearwardly as said foot rest is moved to and fro relative to said seat member, said arms being adjustable to vary the relative movement between said flexible suspension members and foot rest.

In testimony whereof, I hereunto afiix my signature.
